Abstract/ Executive Summary:

The experiment was conducted at Manikganj, Jessore and Dinajpur during 2011-12 to assess the optimum sowing date of newly released tossa jute variety Lal tossa at late jute seed production season. The experiment was laid out in RCBD design with three replications. The cultivar O-72 was used as control. Different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September and study materials Lal tossa and control variety BJRI Tossa Pat-4 (O-72) were used as treatments. The seed crop was harvested at proper maturity of the fruits. Results revealed that the highest seed yields were obtained from Manikganj sown on 30 July which was followed by Jessore sown on 30 July and Dinajpur sown on 15 July. The lowest seed yield and yield attributes recorded on 15 September sowing at all the locations. All other variables were also gave the highest results according to seed yield.

Keywords: Jute, sowing date, late jute seed.

Location: Jute Agriculture Experimental Station, Manikganj, Jute Research Substation, Jessore and Dinajpur

Start Date: 31-07-2011

End Date: 31-01-2012

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

To optimize the sowing time for Lal tossa jute in late jute seed crop.

Methodology:

The experiment was conducted at Manikganj, Jessore and Dinajpur during 2011-12. The experiment was laid out in RCBD design with three replications. Five different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September regarded as treatment. Lal tossa was used as study material and BJRI Tossa Pat-4 (O-72) was control. Unit plot size was 4.0m x 2.5m. Space between plot to plot and around the field 1.0m and between replications 1.5m. were maintained. Seeds were sown in line of 30 cm apart. Cultural and intercultural practices were attended as per BJRI's recommendation.
